Description
Technical field
The present invention relates to drilling wastes processing technology field more particularly to a kind of drilling wastes brick-making methods.
Background technique
Drilling wastes are petroleum, natural gas or other mineral generated in deep prospecting and exploitation drilling process it is discarded
Object, wherein quantity is maximum, most urgently handle is well drilling waste mud and drilling cuttings.Well drilling waste mud and drilling cuttings these two types drilling well
Waste complicated component, appearance at sticky or semifluid, coloration is big, gradation is poor, viscosity is big, pH value is high, liquid phase object content is high and
Naturally dry and hard process is extremely slow, and dry and hard object easily forms drilling waste mud sample object after meeting water-soaked once again, to emission point and near
The environment in area can generate long-term adverse effect, bring high risks to human lives.
Currently, drilling wastes processing method mainly uses the combination skill such as chemical flocculation, sedimentation, mechanically decoupled, drying
Art by drilling wastes solid fraction and liquid phase part separate, then solid fraction and liquid phase part are handled respectively；
Solid fraction generally takes the processing mode of landfill, stacking, this can not only occupy a large amount of land resource, but also to the danger of environment
Evil still remains；After treatment, a part may loop to the recycling of drilling well link to liquid phase part, but cannot reuse
Part or drilling well after the completion of liquid phase part need purified treatment after could discharge, but the cost of this purified treatment is excessively high,
Therefore a large amount of non-purified liquid phase parts still are temporarily stored in dirty mud sump now, this is a great the difficult problem of environmental protection.
In general, current drilling wastes processing method all suffers from the whereabouts problem of final product, and drilling well is given up
Gurry carries out the common objective that innoxious and recycling treatment is this field.By drilling wastes be solidified into brick may be implemented it is harmless
Change and recycling treatment, and have carried out many trials both at home and abroad, but drilling wastes are solidified into brick in the prior art
Method at least there is problems:
(1) method still without preferably breaking glue desiccation, eliminating pollution.Drilling wastes are that liquid phase and solid matter are close
In conjunction with substance, generally stable is gelatin, wherein these drilling fluids are together with a large amount of water containing a large amount of various drilling fluids
Divide and firmly adsorbed by mud particle, forms sufficiently stable gluey system, can not be isolated under natural conditions.It generally adopts at present
It is matched and will be separated by solid-liquid separation with medicament with modes such as plate compression, hot baking, centrifuges, remix a large amount of cement, lime, fine coal
The materials such as ash, miberal powder, clay carry out solidification brickmaking processing.But due to adsorbing a large amount of drilling fluids on drilling wastes solid particle
In surfactant, the electric layer and water film thickness on particle periphery be big, viscosity is big, difficult dispersion, can not merge with external substance, very
More curing materials can not be wrapped to form continuous solidifying to it；And many pollutants are not eliminated thoroughly；Along with these drilling wells
The big multicomponent of liquid substance has deferred action to curing materials such as cement, and many curing materials lose because cannot get aquation for a long time
Effect, injected volume is very big, therefore the indexs effect such as brick compression strength made is undesirable.
(2) still without ideal brick equipment and mode.There is the precedent for attempting to take sintering processing brickmaking, but is being sintered
Energy consumption is had in the process and has new pollution to generate, and some drilling wastes are not suitble to fire, along with firing
Brick out has the shortcomings such as deformation, discoloration, intensity is low, so the mode of face sintering brickmaking is more satisfactory.And at present mostly
The universal brickmaking machine used, still without being directed to the mating brick equipment of waste drilling object brickmaking, waste drilling object grade
With poor, viscosity is big, liquid phase is high, the indexs such as universal brickmaking machine repressed brick compression strength are very unsatisfactory.To be compressed into
Brick, the sport technique segments such as its pressing mode of required brick equipment, pressure size, the compactness of swivel will have certain specific aim
It just can be with.
(3) performance of non-sintered brick and environmentally friendly stability are undesirable.To really realize innoxious and recycling target,
The compression strength of brick can reach that requirement is also far from enough, and there are also frost resistance, carbonation properties, softening performance, drying shrinkage and suctions
Some basic performances of the bricks such as water rate, which all reach related request, could really realize recycling, and data there is no to show that someone does at present
To these or any degree is accomplished.Recycling is realized, if the environmental protection index of brick is undesirable, still can not achieve
It is innoxious, an effective product or technology are needed, pollutant is effectively controlled, reaches environmental requirement, really
Realize innoxious, recycling.Also show which kind of environment protection control measure someone has done to this brick without data at present.
(4) consumption of drilling wastes is small, at high cost.There are some drilling wastes brick-making technologies, the auxiliary material needed
Material account for 60% of brick producing material or more, cost is excessively high, and the consumption of drilling wastes is too small, and manufactured brick performance indicator and
Relevant criterion cannot be fully achieved in environmental protection index again, have little significance to the improvement of drilling wastes.
Summary of the invention
For above-mentioned shortcoming in the prior art, the present invention provides a kind of drilling wastes brick-making methods, can
Drilling wastes are processed into loose drying at low cost, meet the brick-making raw material of related environmental protection standard, and can finally be made

Disappear the major pharmaceutical of dirty desiccation medicament, each dirty desiccation medicament that disappears is no less than three test groups, and each in each test group
The usage amount of kind major pharmaceutical is that every 100 parts by weight drilling wastes sample is discarded using 1~5 parts by weight major pharmaceutical or the drilling well
The manufacturer's recommended amount of the dedicated dirty desiccation product that disappears of object；The dirty desiccation medicament that will disappear is added in drilling wastes sample, is stirred evenly,
60 DEG C of constant temperature of interior sunning under natural conditions 72 hours for drying 24 hours or being placed at least 5 DEG C of air dry oven are placed in, so
It determines to disappear afterwards dirty desiccation effect and all good test group of cost, and by disappear dirty desiccation medicament and its use of the test group
Measure the major pharmaceutical and its usage amount as the dirty desiccation medicament that disappears for being suitable for the drilling wastes to be processed.
Specifically, the dirty desiccation medicament that disappears is mutually immiscible before being added to drilling wastes to be processed, when the dirt that will disappear
It after desiccation medicament is added to drilling wastes to be processed, preferably immediately begins to stir, at most delay can not surpass to after the completion of being added
10 minutes are spent to start to stir, no matter which kind of mix mode is all to be stirred until homogeneous, crush, loosely for optimum state, until to
It handles after loose condition (of surface) is presented in drilling wastes and stops stirring, then shelving dries at least 72 hours in its natural state, in weather
The shelving sunning time needs to be appropriately extended under conditions of moist or low temperature, disappears to can be completed to drilling wastes to be processed
Dirty drying and other treatment.During shelving sunning, material heap can not freeze or drench with rain, and the heap body of material heap should not be too large, such as fruit
The excessive lost speed that will affect moisture of heap to will affect the progress for solidifying compacting link, while also needing to do booth appropriate
It is thin or turn over cool processing, when especially flowable waste is more, with greater need for making thinner or turn over cool processing.
Further, this disappear dirty drying and other treatment the step of disappear using addition and disposably realize by the way of dirty desiccation medicament pair
Drilling wastes disappear dirty, desiccation and solidification, and treated that drilling wastes become dry, loose, there is graininess and powder
The desiccation material of last shape mixing can need to only use existing after the higher drilling wastes processing of some plasticity index in bulk
Broken and screening plant is crushed and screened, that is, the brickmaking original for becoming dry loose, neat and tidy, meeting related environmental protection standard
Material, can solidify at any time and be pressed into brick, therefore this disappear dirty drying and other treatment the step of be not only not necessarily to according to the prior art using filters pressing,
The modes such as centrifugation, heating are separated by solid-liquid separation drilling wastes, reduce a large amount of energy consumption, time and complexity, save
The costs such as machinery, place, artificial, and solid fraction in drilling wastes and liquid phase part no longer need to individually handle, and pass through
Chemical combination, degradation, chelating, precipitating, dissociation, precipitating, evaporation etc. occurs, and chemically and physically reaction can be by tacky drilling well
Waste becomes dry loose, neat and tidy and the brick-making raw material for reaching related environmental protection standard.
B, building gelling material the step of solidifying compacting: is added into the drilling wastes to be processed after the dirty drying and other treatment that disappears
Material is uniformly mixed, to obtain brickmaking mixture；Using static pressure type brickmaking machine by the brickmaking mixture solidification be pressed into it is closely knit
Degree is not less than 80% adobe.
Wherein, at least one of cement or lime can be used in building cementing material, and the additional amount of building cementing material is
10~15 parts by weight building cementing materials are added in every 100 parts by weight drilling wastes to be processed after dirty drying and other treatment that disappear.For
Adobe compression strength requires situation high and that desiccation material viscosity is big, and building aggregate (example can be added in the brickmaking mixture
Such as: the building aggregate can be using sand or stone), and the additional amount for building aggregate is that every 100 parts by weight disappear dirty desiccation
Treated, and 5~15 parts by weight building aggregate is added in drilling wastes to be processed.The compactness for solidifying the adobe being pressed into is not small
In 80%, otherwise the intensity of adobe can have a greatly reduced quality.
Specifically, static pressure type brick machine uses the common static pressure type brick machine in brickmaking field in the prior art, and the static pressure
Pressure F needed for the brickmaking of formula brickmaking machine2Can according to thickness H1=10cm after the compacting of brick in the case where every square metre of minimum
Pressure F1It is calculated not less than 600 tons, specific formula for calculation are as follows:
In formula, F2Pressure needed for indicating the brickmaking of the static pressure type brickmaking machine；F1Indicate every square metre of minimum pressure, until
It is less 600 tons；S1Equal to 1m2；S2Indicate the real area of pressed brick；Thickness after the compacting of H1 expression brick, is equal to 10cm；H2 table
Show the actual (real) thickness of pressed brick.
Further, the step of which suppresses uses the static pressure type brick machine in brickmaking field to after with the dirty drying and other treatment that disappears
Drilling wastes be primary raw material brickmaking mixture carry out solidification compacting, and define brick equipment pressure size and
The compactness for the adobe being pressed into, so as to so that solidifying the Baking-free green brick performance indexes being pressed into reaches JC/T 422-
The standard of 2007 " non-sintered rubbish tailing-bricks ".
C, intensity maintenance the step of intensity conserves: is carried out to the adobe.
Specifically, carrying out intensity maintenance to the adobe is to guarantee the key link of finished bricks performance, if maintenance is not
In place, the performance indicators such as compression strength, the surface hardness of finished bricks be will affect.The step of intensity conserves can be according to existing system
Green strength maintenance process in brick technology is handled, but pays particular attention to following item:
(1) solidify after being pressed into adobe of the compactness not less than 80%, maintenance canopy should be immediately placed in or covered with plastic cloth,
It outdoor can not put too long, otherwise can make the sharply dehydration of adobe surface.
(2) adobe of just compression moulding must handle with care, avoid collision and shake, and moving if necessary must be certain wait have
Intensity after carry out again.
(3) in the case where avoiding outdoor put, if curing temperature is greater than 20 DEG C, the curing time of adobe is generally 28
Curing time must be appropriately extended if curing temperature is 5~20 DEG C in it, but curing temperature is minimum must not be lower than 5 DEG C.
(4) after the adobe of just compression moulding need to park 3~6 hours (depending on rate of drying) in maintenance canopy, start watering and support
Shield, when watering in first 24 hours unavailable violent water injection, water is also not easy excessive, and permeable maintenance is once after 24 hours.During maintenance
It remains wet, is sure not to do suddenly suddenly wet.
(5) preferably adobe overall process is maintained in maintenance canopy or under the state that covers, in favor of keeping the temperature and protecting during conserving
Wet, it is optimum efficiency that moisture diffusion to the surface inside brick body, which forms dewdrop shape (being commonly called as " perspiring "),.If condition does not allow,
Conserving the time in canopy must not be lower than 7 days.
D, the step of implementing environmentally friendly plugged zone: the adobe for completing intensity maintenance is sprayed using aqueous waterproofing paint,
Coating is impregnated, so that the environmentally friendly plugged zone with a thickness of 1~10mm is formed on the surface for the adobe for completing intensity maintenance, after drying
Obtain finished bricks.
Wherein, the aqueous waterproofing paint using silanes aqueous waterproofing paint, organic silicon aqueous waterproofing paint or
At least one of methane-siliconic acid salt aqueous waterproofing paint.
Specifically, stability, resistance to as using the drilling wastes after the dirty drying and other treatment that disappears as brick made of primary raw material
Long property and the feature of environmental protection are relatively fragile, restrict innoxious, resource type treating development always, and the invention proposes uses
Aqueous waterproofing paint implements one layer of environmentally friendly plugged zone on the surface for the adobe for completing intensity maintenance, so as to improve finished bricks
Ageing resistance, hydrolysis resistance, freezing-thawing resistance, resistance to corrosion and environmentally friendly stability.
Further, the step of implementation environmental protection plugged zone at least has following technical effect that
(1) the environmentally friendly plugged zone has obstructed brick body and extraneous generation mass exchange: because the composition of raw material of brick is extremely multiple
It is miscellaneous, it can be chemically reacted over time with the Cucumber in nature, and it is unknown to generate which kind of pollutant, and
The environmental protection plugged zone can obstruct brick body and extraneous generation mass exchange, prevent the hidden danger that new pollutant generates.
(2) ability of closing package pollutant is consolidated and reinforced to the environmentally friendly plugged zone: the environmental protection plugged zone is in brick body
Surface forms the hard shell for being considered as 1~10mm thickness, there is very strong hydrophobicity, and moisture will not pass in and out brick body through shell, so as to
Effectively prevent pollutant in brick body to be precipitated.
(3) the environmentally friendly plugged zone improves the whole ageing resistance of brick body: the environmental protection plugged zone can tolerate pH value for 3~
12 water environment, stability is high, can be permanently effective under circumstances；The environmental protection plugged zone can also defend air, ultraviolet light
Injury of the equal aging actions to brick body, thus the comprehensive ageing resistance for improving finished bricks, hydrolysis resistance, freezing-thawing resistance,
Resistance to corrosion and environmentally friendly stability.
To sum up, drilling wastes can be processed into loose drying at low cost, meet correlation by the embodiment of the present invention
The brick-making raw material of environmental protection standard, and can be finally made compression strength, ageing resistance, hydrolysis resistance, freezing-thawing resistance,
Resistance to corrosion and all ideal finished bricks of environmentally friendly stability, to realize the innoxious and recycling of drilling wastes
Processing.
